Description

本発明はディスプレイパネルに関し、特に有機ＥＬディスプレイパネル及びその製造方法に関する。   The present invention relates to a display panel, and more particularly to an organic EL display panel and a manufacturing method thereof.

近年、表示装置の大型化に伴い、占有空間の小さい平板ディスプレイパネルへの要求が増大しているが、このような平板ディスプレイパネルの一つとして、有機ＥＬディスプレイパネルが注目されている。有機ＥＬディスプレイパネルは、非常に薄く、マトリックス形式でアドレッシングでき、１５Ｖ以下の低電圧で駆動可能であるという長所を有する。   In recent years, with an increase in the size of a display device, demand for a flat display panel with a small occupied space has increased. As one of such flat display panels, an organic EL display panel has attracted attention. The organic EL display panel is very thin, can be addressed in a matrix form, and can be driven at a low voltage of 15 V or less.

このような有機ＥＬディスプレイパネルの製造において、フルカラーを実現するには様々な方法があるが、その中で最も発光効率が優れているのはシャドーマスクを用いる方法である。   In manufacturing such an organic EL display panel, there are various methods for realizing a full color. Among them, the method using a shadow mask has the highest luminous efficiency.

図４は、一般的な有機ＥＬディスプレイパネルの製造工程を示す断面図であり、図５は、図４に示す製造工程で使用されるシャドーマスクを示す平面図である。図４及び図５に示すように、透明基板１上に透明な第１電極２を形成し、その上に隔壁（図示せず）を形成した後、図５に示すシャドーマスク４を用いて赤色有機発光層３−１、緑色有機発光層３−２、青色有機発光層３−３を順次形成する。   FIG. 4 is a cross-sectional view showing a manufacturing process of a general organic EL display panel, and FIG. 5 is a plan view showing a shadow mask used in the manufacturing process shown in FIG.
